TYPE -WRITING MACHINE.

Patented May 5, 1908,.

Application filed May 6, 1904. Serial No. 206,651.

To all whom it may concern:

Be it known that I, CnARLns A. MOREY, citizen of the United States, and resident of Mohawk, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type Writ ing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to the type. ac tions thereof, and the object of my invention is to provide a simple, eflicient and easy type action and one in which the individual parts may be readily assembled and disconnected and removed when desired without the neocssity of disn'munting other parts of the structure.

To the above and other ends which will heretypewriting machines to illustratemy inven-.

tion in its application thereto. Fig. 2 is an enlarged fragmentary plan view, partly in section, of a type bar and hanger.

While I have shown my invention applied to a front-strike or visible machine, it should be understood that so far as certain features of my invention are concerned they may be applied to various styles of typewriting machines.

The frame of the machine comprises a base 1,-'corner posts 2 and a top plate 3, and a suit-v able carriage (not shown) is mounted above the top plate and carries a platen ft The top plate of the machine is cut away or apertured at 5 to, enable the type bars to move from the normal position represented in full lines to the printing position indicated in dotted lines in Fig. 1.

A- pivot rod 6 extends from side to side of the machine and is secured to the base and key levers 7 are notched at 8 in order to cooperatewith the pivot rod and to fulcrum thereon. Each key lever is provided with a finger key 9 and arestoring spring 10 cooperates with the'key lever to restore it to normal position and to maintain it against the fulcrum rod 6. Each key lever has an 11 wardly extending arm or rojection 11 t at extends rearwardly at t e upper end portion thereof, as indicated at 12, and carries a laterally extending pin 13 which is received in a slot 14 of an upright straight sub- I lever 15. Each sub-lever vibrates fore and aft of the machine on a fixed pivot 16 near one end thereof and above the key lever; The upper end of each sub-lever has an upwardly extending open ended slot 17 therein;

the diameter 'of which is substantially uniform throughout its length. served that the pin and sloticonnection between the key lever and the sub-lever is intermediate of the ends of the sub-lever and that the slot 14 is in the nature of an upright slot and is open ended and inclined to the r length of the sub-lever and thus affords a means for effecting a ready connection and disconnection between each key' lever and its associated sub-lever. Each type bar 18 has a crank arm or heel 19 that is provided with a laterally projecting pin 20 which is received within the slot 17 of the associated sub-lever.

It will be ob- From an inspection of the drawing it will be observed that the point in the sub-lever where connection is made directly with the type bar, the fixed pivot 16 of the sub-lever and the point of connection between thekey lever and sub-lever are in substantial alinement. I I

' Each type bar is pivoted to a substantially U-shaped single piece of sheet metal hanger 21 by a pivot pin 22 which is riveted at its ends 23 t0 the side-arms of the hanger. A spacing stud 24 is formedwith circumferential shoulders near the ends thereof where the body of the stud joins the reduced ends and the stud extends between the arms of the U-. shaped hanger in order to maintain them properly spaced apart. "The reduced ends of the spacing stud extend through openings in the hanger arms and are riveted at 25 to the hanger arms in order to securely unite the arms at the point of connection formed by the spacing stud. The inner surfaces of each hanger, where they cooperate with the type bar, are formed as fiat bearing faces 26 and each type bar is provided with oppositely disposed outwardly extending circular flanges, ribs or projections 27 which bear at the outer edges thereof against the flat bearing faces of the hanger, thus forming close oints with the bearing faces of the hanger which tend to prevent the who; sion ofdust, grit or rubbars. It will be seen that the circular ribs or flanges are concentric to the pivot 22 and form cylindrical housings-on each side of the pivotal bearing between the type bar andpivot, and that inclosed chambers 28 are formed on opposite sides of the bear-mg be tween the type bar and its pivot. The circular flanges 27 thus project outwardly from the type bar and overlap the pivotal bearing between the typevbar and pivot 22 and prevent the admission of dust to said bearing. I The inclosed chambers 28, between the cheek plates of the hanger and formed in part by the flanges 27,: may containja lubricant for the type'barbearings. By a further heading of the'pivot pin or rivet 22 the cheek u plates may be brought closer together, thus compensating for any wear which may take place between the/bearing edges of flanges 27 and the cheek plates of the-hanger, and so as p to prevent lateral deflection of the type bar to prevent an undue pressure of the side arms of the han er being exerted upon the bearing edges of t e flanges 2?. By reason of the dis osition of the circular flanges at a considera le distance from the pivotal center of the type bar, said flanges'in their cooperation with the bearing faces of the hanger effectually prevent a lateral deflection of the bar during the printing movements thereof and accurately guide the type barin a radial plane.

Each type bar is secured to a type bar segment 29 by a'headed screw 30; the head of the screw bearing on the upper edge of the hanger while the stem of the screw projects through the hanger and is received in a threaded opening in a flange 31 which pro jects forwardly from the lower edge of the segment. The segment itself Ina oe secured to the top plate of the machine by sore 32. The forward ends ol'ithe type bars rest pon a pad 33 supported by a member 34 secured by a screw 35 to the frame of the machine.

From the foregoing description it will be understood that each individual type bar may bereadily connected to or disconnected lroni' its asscciavtml subdever by merely seat i i cnloving it from the uplev'cr, when the screw ranger in place is re "of the rear end of a- 7 I etension of its spring 10 ill displace'tlie'bearing portion 8 of-the keyl lever from its fulcrum rod and will remove the pin 13 from the inclined slot in the associated sub-lever, so that the key lever may be readily connected to or disconnected from the su b-lever.

In the operation of the machine a depress'ion of a key lever will produce a forward movement of the associated sub-lever around its fixed pivot 16 to the dotted line position shown in Fig. 1, and this movement is efl'ective to turn the type bar on its pivot central When pressure on the finger key is released, the parts will be restored to their normal positions by the ,re-

to the printing position;
